Breath­ing new life into river

Southern Gazette (South Perth) - - Canning River -

THE im­pact of al­gal blooms and num­ber of fish deaths in the Can­ning River is likely to de­crease thanks to the com­ple­tion of a third oxy­gena­tion plant.

The $1 mil­lion plant has dou­bled the ca­pac­ity to pro­vide oxy­gen re­lief to the en­vi­ron­ment up­stream of the Kent Street Weir.

En­vi­ron­ment Min­is­ter Al­bert Ja­cob said the new plant would en­sure an ex­tra 2.2 kilo­me­tres of the river could have ad­e­quate oxy­gen lev­els at all times.

When oxy­gen lev­els are low, it can harm aquatic life. Sum­mer and au­tumn is when lev­els can fall be­cause of the de­com­po­si­tion of ex­cess or­ganic mat­ter and nu­tri­ent.

Ad­e­quate oxy­gen lev­els help pro­vide a refuge for fish, im­prove nu­tri­ent cy­cling, speed up the break­down of or­ganic mat­ter and pre­vent of­fen­sive odours.

Mr Ja­cob said the Gov­ern­ment had also in­vested $1.4 mil­lion to up­grade the two older oxy­gena­tion plants up­stream of the Kent Street Weir.

They ser­vice 2.3km of the Can­ning River.
